Additional Notes

  • The Porsche 718 Boxster 982 uses a semi-automatic transaxle that is serviced in two separate fluid sections: a clutch part and a transmission part, each holding a distinct fluid volume.
  • The clutch part of the transaxle holds 5.4 liters across all listed configurations and model years, indicating a consistent fill volume for that section regardless of trim level.
  • The transmission part of the transaxle holds 3 liters in the base 718 Boxster across all listed configurations, while the 718 Boxster S and 718 Boxster GTS specify a slightly larger 3.2-liter capacity for the same section.
  • The 0.2-liter difference in transmission part capacity between the base model and the S and GTS trims reflects a trim-level variation rather than a model year change, as the base 718 Boxster retains the 3-liter figure from 2016 onward.
  • All listed configurations share an identical service interval of 144 months or 120,000 miles under normal use conditions, applied uniformly to both the clutch part and the transmission part of the transaxle.
  • A 144-month interval equals 12 years, placing the 718 Boxster 982 transaxle fluid among the longer-interval automatic transmission service schedules, consistent with sealed or lifetime-fill designations used by several European manufacturers.
  • All intervals are specified under normal use conditions only, meaning the 144-month/120,000-mile figure applies to standard driving rather than any severe or track-use classification.
  • The 718 Boxster GTS appears only in the 2018-2020 range within the listed specifications, carrying the same 5.4-liter clutch part capacity as all other trims and the 3.2-liter transmission part capacity shared with the 718 Boxster S.
